Abstract (en)
[origin: US2004167460A1] An electrode assembly for use in an iontophoresis device for the transcutaneous administration of an active therapeutic species includes a base layer of conductive material which is consumed (oxidizes or reduces) preferentially to water, a first upper layer of sacrificial material coated on a first portion of the base layer wherein the sacrificial material is consumed preferentially to the conductive material of the base layer. A second upper layer of non-conducting material is coated on a second portion of the base layer, the second upper layer being spaced from the first upper layer, a narrow exposed linking area of the base layer material remaining therebetween. The exposed linking area of the base layer extends across the base layer. During operation of an associated iontophoresis device, the sacrificial material will be sequentially consumed; the first upper layer will be followed by the exposed linking area of the base layer which severs the base layer thereby breaking circuit continuity in the device.
